Abstract The “dragon-eye” fruits produced by the tropical longan tree are rich in nutrients and antioxidants. They suffer from post-harvest enzymatic browning, a process for which mainly the polyphenol oxidase (PPO) family of enzymes is responsib

In this study, we investigate the effect of enzymatic browning on the phenolic composition of apricot in vivo and in vitro. The in vitro browning was caused by the recombinant latent apricot polyphenol oxidase (L-PaPPO). Successful heterologous expre

Abstract Tyrosinases and catechol oxidases belong to the polyphenol oxidase (PPO) enzyme family, which is mainly responsible for the browning of fruits. Three cDNAs encoding PPO pro-enzymes have been cloned from leaves of Malus domestica (apple, MdPP

The present research investigates the long term inhibition of enzymatic browning by inactivating the polyphenol oxidase (PPO) of apricot, using combinations of plant proteases and ascorbic acid (AA). The selected proteases were able to inactivate PPO

Tyrosinases (TYRs) catalyze the hydroxylation of phenols and the oxidation of the resulting o‐diphenols to o‐quinones, while catechol oxidases (COs) exhibit only the latter activity. Aurone synthase (AUS) is not able to react with classical tyros

Tyrosinases catalyse both the cresolase and catecholase reactions for the formation of reactive compounds which are very important for industrial applications. In this study, we describe a proteolytic activity of tyrosinases. Two different tyrosinase

We investigated the bi-colored dahlia cultivar 'Seattle', which exhibits bright yellow petals with white tips, for its potential use as a model system for studies of the anthochlor biosynthesis. The yellow base contained high amounts of the 6'-deoxyc
